15KG Slam Ball

GravoMax Slam Ball – 15KG

Overview

The GravoMax Slam Ball 15KG is built for athletes who want heavier slam ball training with strong resistance and stable control. At this weight, each rep demands full-body engagement, making it a practical choice for explosive strength work, high-output conditioning, and serious training progression. This model is well suited to functional training, CrossFit-style workouts, and HYROX-focused sessions where power, grip, and repeatable movement quality need to hold up under fatigue.

Why choose the 15KG slam ball

The 15KG weight is a strong choice for strength conditioning and advanced progression. It delivers enough load to challenge power output and muscular endurance while still allowing controlled, repeatable slams in structured training blocks.

It is especially useful for athletes moving up from 12KG who want a more demanding training stimulus for explosive conditioning, core-driven movement, and full-body strength-endurance work.

• 15KG resistance for heavier power and conditioning work
• Suitable for advanced progression from mid-range weights
• Built for repeated slams with controlled movement quality

Grip and construction

The ball uses a durable rubber shell filled with sand for a non-bounce slam ball feel. This helps absorb impact and keeps the ball grounded after each rep, which supports safer and more efficient training during high-intensity sessions.

In addition, the tire-tread texture improves grip during overhead slams, front-loaded holds, and rotational drills. The heavy-duty outer construction is designed to handle repeated high-impact use in both home and commercial training environments.

Best for

• Advanced strength-conditioning progression
• Explosive power and endurance circuits
• Heavy slam intervals and repeated power reps
• Functional fitness and HYROX-style training
• PT studios and commercial gym conditioning zones
